ENGLEWOOD, Colo. --Safety Darian Stewart, right guard Ron Leary and defensive end Zach Kerr are all questionable on the Broncos' final injury report of the week in advance of Sunday's game against the Dallas Cowboys.
Kerr practiced all three days this week after missing Monday's game because of a knee bruise, while Stewart practiced Thursday and Friday after sitting out Wednesday's work because of a groin injury he suffered in the fourth quarter of Monday's win over the Chargers.
"Darian looks good, and I'm hoping he continues to progress and play in the football game," Joseph said.
Leary saw limited work Friday after sitting out the previous two days. He stood on the sideline taking mental repetitions Thursday and Friday as he works through the league-mandated post-concussion protocol, which has five steps.
"There's a couple of more things he has to pass before he can play," Joseph said.
Before Friday's practice, which took place without helmets, the Broncos officially placed defensive end Jared Crick on injured reserve because of a back injury. They signed former Browns and Seahawks nose tackle Ahtyba Rubin to fill the vacant spot on the 53-man roster.
"[Crick] had a great day Wednesday, and he was really sore on Thursday, so after further examinations, he needed surgery," Joseph said. "It was a disc in his back."
Running back Devontae Booker (wrist), cornerback Brendan Langley (sprained knee) and quarterback Paxton Lynch (sprained right shoulder) were ruled out for Sunday's game.
In Dallas, linebacker Anthony Hitchens (knee) and cornerback Orlando Scandrick (hand) were officially ruled out for Sunday's game. Neither practiced this week. Wide receiver Terrance Williams practiced Friday after sitting out the Wednesday and Thursday sessions because of an ankle injury; he is questionable. Also questionable is safety Byron Jones; he has been limited the last two days because of a groin injury.
Dez Bryant vs. Aqib Talib is just one matchup to watch when the Broncos host the Cowboys on Sunday.
